For convenience of understanding of the embodiments of the presentdisclosure, the following provides detailed descriptions using variousembodiments.

As shown in FIG. 3, the mobile communications device may be a commonmobile communications device such as a mobile phone or a tabletcomputer.

FIG. 5 shows a recessed structure 21 of the touchscreen 20, and FIG. 6shows a step structure 11 of the housing 10. The touchscreen 20 in theforgoing embodiments is adhered to the supporting surface of the housing10. In an embodiment, two ends of the housing 10 are provided with stepstructures 11 that are opposite to each other, a step surface of thestep structure 11 is the supporting surface, and the touchscreen 20 isadhered to the step surface. The touchscreen 20 is provided with therecessed structure 21 that matches the step structure 11 such that thetouchscreen 20 can be flush with an upper surface of the housing 10. Theupper surface is a plane at a highest location of the two ends of thehousing 10 in FIG. 3. When the structure is used, the step surface isprovided with a double-sided tape 40 or dispensing glue, and the housing10 is adhesively connected to the touchscreen 20 using the dispensingglue or the double-sided tape 40.

Referring to FIG. 4 and FIG. 7 together, the sealing piece 30 is along-strip-shaped sheet-like object, a width of the sheet-like objectcorresponds to a thickness of the housing, and a thickness of thesheet-like object is a width of a frame of the entire device. In anembodiment, a width of a side surface of the sealing piece 30 is thewidth of the frame of the entire device. Besides, after assembly, oneside surface of the sealing piece 30 is flush with a surface of thetouchscreen 20 that is away from the housing 10, and another sidesurface of the sealing piece 30 is flush with a surface of the housing10 that is away from the touchscreen 20. In an embodiment, one sidesurface of the sealing piece 30 is flush with an outer surface of thetouchscreen 20, and another side surface is flush with an outer surfaceof the housing 10. In an embodiment, an exterior of the entire mobilecommunications device is integrally flush, and a case in whichappearance is affected because connection locations among components arenot flush is prevented. In addition, when the mobile communicationsdevice is in use, by means of the foregoing structure, the sealing piece30 is not easy to separate from the housing 10 and the touchscreen 20under an external force such that adhesion stability of the sealingpiece 30 is improved.

When a connection is performed, a surface of the sealing piece 30 thatis towards the housing 10 is adhered with the double-sided tape 40 orthe dispensing glue, and the sealing piece 30 is separately connected tothe housing 10 and the touchscreen 20 in a sealed manner using thedouble-sided tape 40 or the dispensing glue.

To improve connection strength of the sealing piece 30, preferably, thesealing piece 30 is a metal sealing piece 30 which has relatively goodstrength, and connection strength between the housing 10 and thetouchscreen 20 is improved. In addition, when the metal sealing piece 30is used, the metal sealing piece 30 can well protect the touchscreen 20and the housing 10, and when the mobile communications device falls byaccidence or touches other objects, a metal connection piece at a sidesurface can provide good protection and prevents the touchscreen 20 frombeing damaged.

In an embodiment, when the sealing piece 30 is connected to the housing10 and the touchscreen 20, different connection structures can be used,and the following provides descriptions using various embodiments.

Embodiment 1

A length of the sealing piece 30 is the same as a length of the housing10, and two end surfaces of the sealing piece 30 are respectively flushwith two end surfaces of the housing 10.

When the forgoing structure is used, two ends of the sealing piece 30are separately exposed, and the two exposed end surfaces arerespectively flush with the two end surfaces of the housing 10, therebyensuring regularity of appearance of the mobile communications device.In addition, by means of the forgoing structure, a structure of aconnection location among the sealing piece 30, the touchscreen 20, andthe housing 10 is relatively simple, which facilitates adhesion.

Embodiment 2

As shown in FIG. 6 and FIG. 7, each end of the housing 10 extendstowards two sides of the housing 10 to form protruding structures 12configured to cover the sealing piece 30, and a length by which eachprotruding structure 12 extends is the same as the thickness of thesealing piece 30.

In the forgoing structure, the two ends of the housing 10 extends toform the protruding structures 12 configured to cover the sealing piece30. In an embodiment, protruding structures 12 formed at two ends ofeach side of the housing 10 form a clamped structure, and the sealingpiece 30 is exactly clamped between the two protruding structures 12.Two ends of the sealing piece 30 are wrapped using the forgoingprotruding structures 12. In addition, the protruding structures 12 forma locating structure such that the sealing piece 30 is easy to beinstalled. In addition, when the mobile communications device is subjectto an external force, the forgoing protruding structures 12 can preventthe sealing piece 30 from being subject to a force that causes thesealing piece 30 to be misplaced such that connection strength betweenthe sealing piece 30 and the housing 10 and connection strength betweenthe sealing piece 30 and the touchscreen 20 are improved.

In addition, the protruding structure 12 further provides a contactsurface between the sealing piece 30 and the housing 10, and, thesealing piece 30 is separately adhesively connected to the protrudingstructures 12 that are located at two ends of the sealing piece 30.Therefore, the connection strength between the sealing piece 30 and thehousing 10 is further improved.

It can be seen from the forgoing descriptions that when the sealingpiece 30 is connected to the housing 10 and the touchscreen 20,different connection structures may be used. However, it should beunderstood that the forgoing Embodiment 1 and Embodiment 2 merely listtwo structures, and a connection structure among the sealing piece 30,the housing 10, and the touchscreen 20 provided in this embodiment mayuse other connection structures.
